【摘要】 A mode-locked external-cavity laser emitting at 1.17-μm wavelength using an InAs/GaAs quantum-dot gain medium and a discrete semiconductor saturable absorber mirror is demonstrated.By changing the external-cavity length,repetition rates of 854,912,and 969 MHz are achieved respectively.The narrowest-3-dB radio-frequency linewidth obtained is38 kHz,indicating that the laser is under stable mode-locking operation.更多还原
